HEATING-LAMP.

SPECIFICATION forming part of Letters Patent No. 332,370, dated December15, 1885.

Application filed December 23, 1.884. Serial No. 151, 65. (No model.)

' To all whom it may concern:

Be it known that I, AUGUST F. ZIMMER- LING, of Milwaukee, in the countyof Milwaukee, and in the State of Wisconsin, have invented certain newand useful Improve ments in Heating-Lamps; and I do hereby declare thatthe following is a full, clear, and exact description thereof.

My invention relates to the burning of vapor, mainly for heatingpurposes, and will be fully described hereinafter.

In the drawings, Figure 1 is a perspective view of my invention. Fig. 2is a section on line a: a: of Fig. 4. Fig. 3 is a section on line 3 y ofFig. 4, and Fig. 4 is a. vertical section of my device on an enlargedscale.

I use two reservoirs with my device, the reservoir A preferably tocontain a more volatile burning-fluid than reservoir B. O is a pipe thatleads from reservoir A, to be joined to an upright tube, C, by acoupling, D, and this coupling D has a stuffing-box, D, through whichthe valve-shaft d passes on its way to a screw-threaded bushing, a,fixed to the upper end of the tube 0, which is preferably in sections.On its upper end the shaft (1 is provided with a needle-Valve, (1, whilea housing, (P, that carries the valve-seat, is screwed onto the upperend of the tube 0, that part carrying the seat being reduced to receivethe tip 6, which is perforated to admit air to the gas as it passes outof the valve-orifice. The housing d has screw-threads about its upperend to take the screw-threaded shield E, that is also perforated nearits lower end, and which preferably has female screw-threads at itsupper end, to which is attached the burner E. The tube 0' extends upthrough a burner for heavier fluids. This burner consists of an outershell, F, which is perforated near its base and joined below theperforations to an inner tube, F, by a ring, f. The inner tube, F, ismuch smaller than tube F, except at its base, where it flares out tojoin the latter, and tube F in turn contains a shorter and smaller tube,F which is also flared at its bottom, so as to make a tight joint withtube F. The space between tubes F and F forms the wickreceptacle forthis burner, and the tube F is recessed on one side, where a chamber, G,is joined to it. In this chamber the shank g of the wick-raiser 9slides, and the latter is controlled by a screw-bolt, H, that passesdown through a screw-threaded nut attached to the outer end of theshank; or this end of the shank may be enlarged and provided with ascrew-threaded aperture, so that the wick I can be raised and lowered byturning the milled head of the screw-bolt. The pipe from the chamber Bleads into the chamber G, and from it the oil flows to the wick, Whilethe fluid from reservoir A flows through pipes O and O, and from thencethrough the packing K in the latter into the housing (1 The tube F ispreferably made in sections, and the upper section is provided with adeflector, a, and a chimney or air-shield, (8, may be fitted to it,which, in turn, may be provided with windows b, for allowing the lightto shine through.

The operation of my device is as follows: The heater is first started bylighting the wick I, which as it burns heats the vapor-burner, and inturn converts the fluid that flows into the housing (1 into gas, whichlatter is let out into the tip by lowering the needle-valve. The tube Fforms a chimney on the inside of the burner, and for feeding the innersurface of the wick-flame, and this tube and tube F form a chimney forthe outside of the same, so that there will always be a sufficient draftto feed the flame and make perfect combustion, with the difference, inthis respect, from other lamps, that I place my draft-tubes belowinstead of above the burner.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The combination, in a heating-lamp, of a vapor-burner free from anywick, and a wick-burner surrounding the latter, and a draft-tubesurrounding the wick-burner and below the vapor-burner, substantially asset forth. V

2. The combination, in a heating-lamp, of a vapor-burner free from anywick, and a wick-burner surrounding the latter, and an outer drafttubewith a deflector parallel with the top of the wick, and an airshieldabove said Wick, but below the top of the vaporburner, substantially asset forth.

3. The combination, in a heating-lamp, of draft and wick tubes F F F,with the chamber G, reservoir B, and pipe from reservoir to chamber,wick-raiser g, with shank g, and In testimony that I claim the foregoingI screw-bolt H, passing through shank 9, subhave hereunto set myhand, atMilwaukee, in stantially as set forth. the county of Milwaukee and.State of Wis- 4.
